TABULATOR-STOP FOR TYPEWRITERS.

Specification of Letters Patent. Patented D430. 13, 1921.

Application filed. October 15, 1920. Serial No. 417,090.

To all to 71-0772, 2'25 may concern Be it known that 1, WILLIAM MoLLn, a citizen of the United States, residing at Oshkosh, in the county of \Vinnebago and State of lVisconsin', have invented a new and use ful Tabulator-Stop for Typewriters, of which the following is a specification.

lhis invention relates to typewriters and more especially to tabulator rails and stops, one of the objects of the invention being to provide a substantial tabulator rail on which a scale is displayed, there being a tabulator stop adjustably mounted on the rail and carrying a pointer which cotiperates with the scale on the rail to give the exact position of the stop with relationto the front paper holder scale whereby the operator may set the stop accurately for any desired position on the paper. p V

A further object is to provide a tabulator stop which is of rigid Construction, is simple and durable, which can be firmly locked in any desired position on the tabulator rail and which, when released, will slide freely along the rail.

A further object is to provide a tabulator stop having a pointer projecting therefrom where it can be seen conveniently above the graduated scale on the rail, the said pointer constituting means for preventing the parts of the stop from becoming separated as long as the stop is in position on the rail.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention-resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings the pre* ferred form of the invention has been shown.

In said drawings Figure 1 is a perspective view of a portion of a tabulator rail and showing two stops in position thereon, one of the stops being locked and the other unlocked.

Fig. 2 is a plan View of one'of the stops and the adjacent portion of the rail.

Fig. 3 is a perspective view of the body member of the stop,

Fig. 4 is a perspective'view of the locking member of the stop.

Fig. 5 is a side elevation of the body ineinber of the stop.

Fig. 6 is a detail view of the blank from which the body member is shaped.

Referring to the figures by characters of reference 1 designates a tabulator rail on one face of which are provided ratchet teeth 2 while on the top of the rail are arranged gracluations 3 forming a scale. The stop used on the rail includes a'body formed of a plate 4 having a depending tongue 5 which can be formed with an opening 6 to receive the screw of the bell cam not shown. pointer or index 7 is extended from the upperend of the plate 4. and extending from the sides of the upper portion of the plate are parallel wings 8 each of which has an angular opening 9 through which the rail 1 is adapted to extend. v

Slidably mounted on the plate 1- and'between the wings 8' is a locking plate 10'having a longitudinal slot 11 through which the pointer or index 7 projects. Extending from the upper end oflthe locking plate is a finger piece 12 and flanges 13 are formed along the sides of this plate 10 and are the wings 8.

It is to be understood that under normal conditions the locking plate 10 is in its lowermost position with its finger piece 12 resting on the top of the plate 4: and with the flanges 13 projecting between certain of the teeth 2. By lifting upwardly on the finger piece 12, however, the plate 10 can be raised so as to withdraw the flanges 13 from engagement with the teeth 2 whereupon the stop can be moved freely to any position desired and then again locked by lowering the plate 10. It will be noted that the index or pointer 7 extends through the slot 11. Thus it becomes impossible to separate the parts 4 and 10 as long as the rail 1 is in position within the openings 9. This index or pointer 7 laps the graduated face of the rail 1 so as to indicate a selected graduation.

Furthermore the flanges 13 on the locking piece 10 are wedge shape, and the angular opening 9 in the wings on the sides of the stop are also cuton an angle with the back surface 4 of the stop, the object being that adapted to slide along the inner faces of I the harder the locking piece 10 is forced down, the tighter the stop andrail will be locked together, entirely doing away with all side play which is so objectionable in a tabulator stop.

W' hat is claimed is i i 1. 'The combination with the tabulator rail of a typewriter having a toothed face, of a stop adjustable along the rail, a pointer projecting from. the stop, a locking member slidable on the stop and held assembled therewith by the pointer, and means on-said member for engaging the toothed face'of the rail to hold the stop against movement upon therail,

2. The combination with the 'tab'ulator' rail of a typewriter having a toothed face,

of a stop including a member having wings provided with openings through whichthe rail extends, a locking member movabilyfl mounted between the toothed face of the rail and the first named member, means thereon for enga in the ad'acent teeth on (J- an as -he rail to hold the members against move ment along the rail. I The combination with the tabulator "ill of a typewrlter havlnga toothed face,

of a stop including a member having wings provided with openings through which the rail extends, a locking member movably mounted between the toothed face of the rail and the firstnamed member, means thereon for engaging the adjacent teeth'on the ,rail to hold the members against movement along the rail, and a finger pieceextending from the tooth engagingmember andnorrnally bearing upon one end of the apertured member.

4. The 1 combination with the tabulator rail of a typewriter having a toothed face,

5. The combination with the tabulator rail of a typewriter having a toothed face, of a body member having apertured wings through which the tabulator rail extends, a

lockingmember slidable between the body member and the toothed face of the rail and having a tooth engaging portion, a-finger piece extending trom'the locking member and beyond the body member.

6 The combination with a tabulator rail of a typewriter having a toothed face, of a body member having apertured wings through which the tabulator'rail extends,

a locking member slidable between the body member and the toothed faceof the rail and having-a tooth engaging. portion, a finger piecexextending from the locking member and beyond the body membensaid, locking member having a longitudinalslot, and a pointer extending from the body member and through the slotfor holding theflnieinbersassembled whilevin position on the rail.

.In testimony that I claim the foregoing as my own, I have hereto aiiixed n1yrsignature in the presenceof two witnesses.
